Warning Signs to Watch For
Excessive treatment recommendations: Be cautious if a clinic immediately recommends expensive, extensive treatment at the first visit, or claims that even teeth another clinic found healthy need treatment.
Avoidance of cost explanations: If they avoid giving a clear explanation of treatment costs or give vague answers like "we'll decide after treatment," it is worth comparing consultations with other clinics.
Poor emergency response: It is best to avoid clinics that cannot be reached if problems occur after treatment or that respond irresponsibly with comments like "go to another hospital."
Neglected equipment or facility management: If you suspect the sterilization of instruments or worry that the treatment room is too old and hygiene may be an issue, look for another clinic.
Frequently Asked Questions
How much does cavity treatment usually cost?
The cost varies greatly depending on the severity of the cavity. A simple cavity may cost about 10,000-30,000 won with insurance coverage, root canal treatment may cost around 100,000-200,000 won, and if a crown is needed, the total may be around 300,000-500,000 won. Exact costs can be confirmed after diagnosis.
Is anesthesia necessary for cavity treatment?
It depends on how deep the cavity is. Shallow cavities may be treated without anesthesia, but if decay has progressed close to the nerve, anesthesia is essential. If you are sensitive to pain, you can request anesthesia in advance.
What should I be careful about after cavity treatment?
Avoid eating for 2-3 hours until the anesthesia wears off. Avoid hard or sticky foods for 1-2 days, and it is best to chew on the opposite side of the treated area. If persistent pain or swelling occurs, contact the clinic immediately.
How many visits does cavity treatment usually require?
Simple cavities may require 1-2 visits, root canal treatment 3-5 visits, and treatment including a crown may take 5-7 visits in total. This varies depending on your oral condition and the scope of treatment, so please consult your dentist for an exact schedule.
Can a dental clinic specializing in implants also handle cavity treatment well?
Just because a clinic specializes in implants does not mean it neglects cavity treatment. However, since it may focus more on implants than general care, it is a good idea to check its experience and reviews for cavity treatment in advance.
Which clinics offer evening or emergency dental care?
킹콩치과의원 (until 20:30 on Thursdays), 오산본플란트치과의원 (until 21:00 on Mondays and Wednesdays), and 서울늘솜치과의원 (until 20:30 on Mondays and Wednesdays) offer evening care. In emergencies, please call ahead before visiting.
